I try to display Admob ads on Cocos2d-x, It works good on Android, but no luck on Iphone.I follow some tutorials and on RootViewController.mm I implement viewDidLoad method like this

`- (void)viewDidLoad { [super viewDidLoad];

// Create a view of the standard size at the top of the screen.
// Available AdSize constants are explained in GADAdSize.h.
bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];
// Specify the ad's "unit identifier." This is your AdMob Publisher ID.
bannerView_.adUnitID = `“MY\_APP\_ID”;

// Let the runtime know which UIViewController to restore after taking // the user wherever the ad goes and add it to the view hierarchy. bannerView_.rootViewController = self; [self.view addSubview:bannerView_];

// Initiate a generic request to load it with an ad. [bannerView_ loadRequest:[GADRequest request]];}@
